SPECIFICATION forming part of Letters Patent No. 622,458, dated April 4, 1899.

Original application lihwl February 1 2, 1898, Serial No. 670,061. Divided and this application filed December 23, 1898; Serial No. 700,119. (No model.)

T1) Ii/Il'l/O'hl H III/III] I'IIIHIV'TL' lie it known that- I, JEAX BAPTISTE FosnU,

a subject of the King of Belgium, residing in Brussels, in the Kingdom of Belgium, have invented certain new and useful Improvemenls in the Manufacture of Glass Tumblersand I do hereby declare the following to be a I full, clear, and exact deseriptior'i of the invenevenly or uniformly cutting or tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and numerals of rcfcrencc marked thereon, which form a part of this specification.-

The invention herein referred to constitutes a division of the subject-matter referred to in an application for Letters Patent filed by me in the United States Patent Office February 1:2, 1898, Serial No. 670,061.

The invention herein referred to relates to the manufacture of glass tumblers; and it has reference particularly to a machine for trimming off the tops of the blown tumblers.

The invention consists in the improved machine for cutting or trimming 05 the tops of the blown tumblers and in the combination and arrangement of the various parts of said machine, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the'claim.

The invention is fully illustrated in the aceompanying drawings, wherein like letters and numerals of reference indicate corresponding parts in the several figures, and in which.

Figure 1 is a view, partly in side elevation and partly in section, of the machine? Fig." 2 is a top plan view of said machine, and Fig.

3 is a sectional view of one of the tumbler holders or sockets employed in the said machine.

In said drawings, a designates .a base or frame upon which is mounted (being secured thereto by screws or bolts) :1. plate 12. Resting centrally upon the top oil said plate is arranged a collar 0, provided with laterally-projecting arms (I d, integrally formed therewith and bent upwardly at their free ends. Upon the top of saidcollar is revolubly mounted a gear-wheel e, which is rigidly connected with Motion is imparted to the be velgear c from a bevel-pinion g on one end of a drive-shaft g revolubly mounted in brackets 5/ and g and adapted to receive its rotary movement from one of a pair of pulleys g, andmotion is imparted to the worm-wheel g from a worm 72, mounted on a shaft h, .journaled in said brackets g and g and also in a bracket 9, extending downwardly from the frame or base a, said shaft being adapted to take its movement from the drive-shaft through intermeshing pinions 7L2 k carried on said shaft. From the foregoing description of the gearing it will be seen that the gear-wheel is rotatable atahigher degree of speed than the circular plate or disk f.

The circular disk or p ate f is provided with a series of eqnidistantly-disposed orifices or openings i, whereinare adapted to be revolubly mounted the holders or sockets for the reception of the tumblers to be operated upon;

Each of said sockets consists of a cylindrical barrel or cham ber-i,havingan external threading 2' and an internal flange d at its lower as well asat its upper edge, and also having a series of gear-teetli-i, integrally formed upon and surrounding it. 7; indicates the bottom or base of the socket or holder, and 7e indicates the cap therefor, said base and the cap being provided with internal threading which engages the threadingi of the barrel or chamber. The cap 7o is provided with an opening k for the reception of the tumbler I, and between said cap and the upper flange and also between the lower flange and the base 7; 1S arranged an annular elastic cushion if. For a purpose hereinafter to be set forth the socket or holder is provided with a vertically-movable pin or, which is set in a nipple m, integrally formed upon the base k, and which pin is rounded oli at its lower end and carries at its upper end a cushion or pad m suitably connected thereto,as by threaded projection m on said pin. The cap and the surround- -ing teeth of each socket form an annularv recess,into which projects the surrounding edge of'the disk f. The gear-teeth of all of said sockets are in mesh with the teeth of the gearwheel e. Hence it will be seen that while the a rotary movement of its own.

Upon the upwardly-projecting ends of the arms 01 d are arranged one on each arm tracing devices n. Each of said tracing devices consists of a block a, adj ustably mounted by means of nuts 91. 71 upon a' pair of posts n 'and having an opening therethrough extendin g radially with relation to the disk, in which opening is reciprocally mounted a pin 0, car-. rying upon its free end a diamond and normally pressed inwardly by a spiral spring 0 arranged in said opening and disposed be tween an enlargement 0 on said pin and an adjusting-nut 0 situated in the outer end of said opening.

In order to obviate the danger of breakage owing to the sudden impact of the diamond with the approaching and rapidly-rotating tumblers, I have'provided means for moving the diamond slowly to one side as a tumbler approaches it, so that the force of the blow, will be minimized. This is effected by means of a lever 19, fulcrumed at 19' upon a projection p of one of a pair of diametrically opposite standards p bolted to and extending upwardly from the base, said lever being under the control of a spiral-,springp coiled about the pivotal point, which maybe a belt or pin 1), and secured at its free end to a pin 19 on said lever. The free end of said leverp projects between the posts n on the arm and is adapted to be engaged by each of the teeth f on the peripheryof the diskf, so as to impinge against one of said posts W, and thereby move' the arms in the direction of the rotation of the disk. WVhen the lever snaps back under actuation of its spring and after the tooth of the disk has become disengaged therefrom, said lever is adapted to strike against the other of the posts a, so as to return the arms cl (1 to their original position. Rubber buffers q-may be employed to take the impact of the arms in either of.their movements. The ends of the arms (1 d are guided horizontally by rollers 10 and 10 respectively,

' carried by said arms, operating in elongated recesses 19 in the standards 19 7' indicates a device adapted to heat the traced portions of the tumblers as fast as they approach from the tracing device, the consequent expansion making it therefore possible to easily remove the superfluous portion of said tumbler with a smart blow. Said heating apparatus may constitute an ordinary Bunsen-burner device and may consist, essen tially, of a vertically-adjustable tube 4", havin g dame openings or perforations 7' and suit- 8 indicates a pair of dlametricall'y opposite cams mounted upon the disk or plate fand:

adapted to be engaged by thecushioned pins m of the sockets. I

- In operation the newly-blown tumblers are pressed into the sockets at points which Ihave v designated in Fig. 2 by the numerals 1 .and

4, and the machine being in motion said tumblers are carried around to the tracting devices, where the diamonds act, upon them as they rapidly rotate and move past the same, v

so as to'cut off enough to'produce'a tumbler of the desired height. Aseaeh tracing device is approached by its respective tumbler it is acted upon, as and for the purpose heretofore described',by the spring-actuated lever I p. Having passed the tracing device said tumblers approach the burners, where their. traced portions areheated, so that the attendant can easily remove the tops witha slight smart blow, and where their consequently more or less rough edges are somewhat round ed ad by being subjected to theheat thereof.

- When they have passed the heating apparatus, the tumblers are loosened in their socketsby the cushioned pins m, which wipe upon the cams s, whereupon said tumblers may be easily removed from the sockets by the operator. z

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
